Patented May 16, 1921.

Application filed May 2K5, 1920. Serial No. 384,276.

To all whom t 'may concern Be it known that l, `FREDERICK E. DOM- soirnrr, citizen of the United States, residing at Bridgeport, in the county of Fairfield and Statey of Connecticut, have invented certain new and useful Improvements in Sash- Holders; and I do hereby declare the following to be a full, clear,'and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same.

My invention relates to window sash holders whereby the upper and lower sashes are simultaneously held in any of theirfadjusted positions, or one sash can be held in open position at the same time that the other sash is closed. f

Referring to the accompanying drawings wherein the same letters and numerals indicate like parts throughout the several views- .f

` Figure 1 represents. a broken view of a window, broken view of one of the window frames, and a broken view partly in section of the opposite window frame, showing` Ithe sash holder within the latter frame and in position to hold the' sashes against movement.

Fig. 2 is a broken view `of the window, broken view partly in sectionpof the window frame inclosing the sash holder, and its actuating levers, sectional view of the tube .holding the mechanism for actuating the levers.

Fig.v 3 isvan enlarged broken view of the upper end of the window frames, upper end of thesash holder in clamping position with Vrespect to the sashes, and brokenview of the f sashes. 40

Fig. 7 is an enlarged detail broken rearv 'elevation ofthe sash holder showing bars yas substituted for the back plate.

Fig. `8` is an enlarged detail view of the lever actuating crank in neutral position,

and broken Yi/'i'evvofL the connecting link.

Fig. 9 is an enlarged detail view of the crank in open position, and broken View of the connecting link.

F ig. 10 is an enlarged broken sectional view of a part of :the window frame, broken vlew of the stationary bar, and one of the side plates, and

Fig. 11 is an enlarged upper plan view of a modified construction of the sash holder.

The sash holder proper lconsists of the metal strip 1 extending the full length of the window, that is, from the silll 2 to the upper cross bar 3 of the window frame, and is provided with the concave seats or .runways la, lb, to receive the convex edges of the sashes 4, 5. 6 is a metal strip or plate, which, in Figs. 3, 4, and 6, also extends the kfull length of the window, and is held in the embrace of the sash holder by the lapped ends 1c. The rearwardly extending ears 7 of the strip 6 embrace the bar 8 and a portion of the sash holder operating lever 9, see also Fig. 2, the former being rigidly secured to said ears by the rivet 10.

. The stationary metal strip 11 also extends the full length of the window and is held in position by the guide plates 12, 13, resting against the inner facesr of the wooden strips 14, 15, of the window frame, and are of the same length as the sash holder. 16,- Figs. 3, 4, 5, is a rod located in the flanges '11a of thestationary strip 11 and carries the sash holder operating lever 9. One arm of this lever, Fig. 2, engages the bar Sto force the sash holder toward the sashes, and away therefrom by engaging the pin 1'? of the ears 7, in the manner presently to be described.

18, Fig. 2, is a tube providedV with the slots 19 through which'the levers 9 project within the tube. This tube is vertically reciprocated by means of crank 2O and crank shaft 21, seen more clearly in Fig. 10. This shaft is journaled in the ears 22 located at the bottom of the stationary metal strip 11,

and out of contact with the window frame,

so that the entire mechanism ofthe sash holder is entirely independent of any rigid connection with any part of the window frame andy can readily be inserted or removed therefrom, The square end 21a of the shaft isadapted to receive a key, not shown, inserted through the opening 23 in the frame 15.

Referring to Fig. 2, 24, 25, 26, 27, and 28, lare disks pinned .tothe interior of the lbuildings or automobiles, cars, &c.

tube. The connecting rod 29 and link 29a connect the crank 2() with the disk 24, and the levers 9 normally rest on the disks 25. The movable disks 30, 31 and 32, are normally held against the levers by the springs 33, 34, and 35. .The spring 36 is located between the disk 24 and the closed end 37 of the tube.

Turning the crank 20 into the lowest position as shown in Fig. 2 will draw the tube down and compress alll lof the springs therein. The compressed action of the springs 33, 34, and 35, will actuate the levers 9 and force the sash holder irmly against both sashes. Turning the crank 2O into the neutral position, shown in Fig. 8, will elevate the tube and actuate the levers to release the locking pressure of the holder just enough to permit the sashes to be raised and lowered and are held in any of their adjustedpositions simply by means of the rictional contact of the holder with the sashes. 38, Fig. 3, is a stationary metal run-way strip located in the opposite part 39 ot the window frame. This strip is also provided with the concave seats or run-ways 38a to receive the opposite convex edges of the sashes. Wvhen the crank 2O is turned into ythe position shown in Fig. 9, the sash holder will be drawn back into the position shown in Fig.`4. This will provide suiiicient end room for the lateral movement of the sashes in the direction of arrow a until clear of the run-way strip 38, Fig. 3, Vwhen they can be swung around and removed clear of the window frames for the purpose of washing the window panes 40. Openings, one of which, 41, Fig. 5, are formed through the metal strip 11 to admit the ears 7 when the sash holder is retreated.

The short bars 42, Fig. 7, could be substitutedv for the long metal strip 6 having the same ears, and these bars held in the embrace of the sash holder in theY manner described for the strip 6.

The sash holder could beconstructed of wood as shown in Fig. 11, and operated in like manner as the 'metal construction or in any other manner desired. However, the metal .holder is preferable as it is not only cheaper and lighter but more durable.

The advantage of the above described sash holder is that it can be inserted in any window frame without altering the construction or general character of the frame, and this applies to both sides of the frame.

. When the holder is brought into forcible engagement with the sash, they' are practically air tight, and free from any possibility of rattling. This insertible feature of the holder renders it particularly adapted for any and all kinds of window frames, for The concave seats or run-ways of the movable sash holderand the metal run-waystrip 38 may vary as to the degree of concavity which may be very slight, or even straight, with the edges of the sashes correspondingly shaped thereto. However, a certain degree o' concavity for the run-ways, or seats, and the edges of the sashes shaped to conform thereto, will result in a closer fit and an increased clamping elfect.

The guide plates 12-13 form an inseparable part of the elements that make up the combination shown in Figs. 3 and 4. The curved ends 12a-13aN are secured to the stationary strip 11, and the curved ends 123--13b rest against the frame 14-15, so that all of the elements are inserted or removed together.

l Having thus described my invention what I claim as new and novel is l. In combination with a window frame and window sashes therein, a rigid seat commonv to both sashes for engaging the end face of each, a holder common to both sashes and engaging the opposite end face of each, and means to move the holder in the plane of the sashes so as to bodily shift the latter in said plane and against the rigid seat.

2. In combination with a window frame and window sashes therein, a rigid seat common to both sashes :tor engaging the end face of each, a holder common to both sashes and engaging the opposite end face of each, and means to move the holder in the plane of the sashes so as 'to bodily shift the latter in said plane and against thefrigid seat, said means including horizontally pivoted and vertically movable spring pressed devices which act upon the holder.

3. In combination with a window Jframe and window sashes'therein, a seat for engaging'each of the sashes,` a holder engaging each of the sashes, and means to move the holder and thereby the sashes against the seat including a tubular slotted member, bellcranks having one end bearing against the lholder and thereby the sashesL against the seat including a spring tensioned device c which at one end engages the holder and means for tensioning the spring to cause the latter to eXert tension on the holder.

' 5.1m combination with a window frame and window sashes therein,.a seat for engaging each of the sashes, a holder engaging each of the sashes, and means to move the holder and thereby the sashes against the seat including a series of spring tensioned devices which at one end engage the holder, a vertically movable member common to all of the devices and engaging the opposite ends thereof, and means whereby vertical move ment of the member in one direction will effect compression of all of the springs and in the opposite direction will allow of eXpansion of the springs.

6. In combination with a window frame and window sashes therein, a rigid seat common to both sashes for engaging the end face of each, a holder common to both sashes and engaging the opposite end face of each, and means to move the holder in the plane of the sashes so as to bodily shift the latter in said plane and against the rigid seat, the rigid seat and the holder each having concave portions and the said end faces of the sashes being correspondingly shaped.

7. In combination with a window frame and window sashes therein, a seat for the end face of each of the sashes, a holder for engaging the opposite end face of each of the sashes, a metal strip of U-cross-section having the free edges of its sides abutting the rear face of the holder, the sides of the holder being engaged over the outer faces of the sides of the Ushaped strip and turned inwardly and engaged with the rear face of the strip, substantially S-shaped guide plates engaged at one end with the inner side faces of the window frame, a second strip engaged in the opposite ends of the guide plates, and operating devices carried by the second strip and engaged with the U-shaped strip to actuate the holder.

8. In combination with a window frame and the window sashes therein, a pair of spaced metal guides having front portions formed to abut the inner sides of the frame and having rear portions turned inwardly, a member secured to the rear portions, a sash holder slidable between the guides, and means carried by the member and engageable with the holder to move the latter into and out of engagement with the sashes.

9. In combination with a window frame and window sashes therein, a pair of spaced metal guides, insertible in the window frame by sliding thereof, a sash holder slidable in the space between the guides, supporting means between the rear sides of the guides, and means carried by the supporting means and engaged with `the holder to slide the latter. l

10. In combination with a window frame and the window sashes therein, a pair of spaced metal guides, insertible in the window frame by sliding thereof, a sash holder slidable in the space between the guides,support ing means between the rear sides of Vthe* guides, means carried by the supporting means and engaged with the holder to slide the latter, and means associated with the guides and engageable with the inner sides of the window frame to restrict inward movement of the guides.

In testimony whereof I affix my signature.
